Yup, rocket stove DIYs are easy to find, but to each his own and if I can afford to spend $150 on a good knife, I can also afford to spend the same on a rocket stove that’s good looking, lightweight, extremely portable and a one-time buy. It’s the kind of thing I wouldn’t mind pulling out in front of the sheeple to have a BBQ or go camping with, and that makes me happy one way or another. Just like the rain barrel, I could DIY one myself, but it’s unlikely to look even a fraction as good (especially with my incredibly poor DIY skills), and so I’d rather just buy one and be done with it.
His answer was squarely in line with Prepper doctrine. Dr. Redlener said it was rational — indeed, it was recommended — to have a three-day supply of food and water, a working flashlight, a first-aid kit, a radio that runs without batteries and a plan in place to rejoin one’s relatives after a disaster. He talked about situational awareness, a major Prepper mantra. “A prepared citizen is someone who understands how to take care of himself,” he said, “who has amassed the necessary items, who has a plan.”
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
